Instrument cluste
r 123Instrument cluster
You will find an illustration of the instrumen t
cluster in the "At a glance" section
( Y page 28). G
Risk of accident
No messages can be displayed if instru -
ment cluster and/or the multi-function dis-
play fail .
This means that you will not see information
about the driving situation, such as the
speed, outside temperature, warning/indi-
cator lamps, display messages or system
failures. The vehicle's handling character-
istics may be affected. Adjust your driving
style and speed accordingly.
Immediately consult a qualified specialist
workshop which has the necessary special-
ist knowledge and tools to carry out the
work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, work relevant to safety or on safety-
related systems must be carried out at a
qualified specialist workshop. Activating the multi-function displa
y
X Switch on the ignition.
The multi-function display is also activate d
when you switch on the lights or open th e
driver's door. Adjusting the instrument cluster

X Brighter or dimmer: turn clockwise or

e
The coolant temperature gauge is in the
instrument cluster on the left-hand side. The
coolant temperature may rise to 120 †under
normal operating conditions and if the con-
centration of antifreeze/corrosion inhibitor is
correct. The coolant temperature may rise to
the top end of the scale at high outside tem-
peratures and on long uphill stretches. Resetting the trip meter
Vehicles with a 4-button multi-function
steering wheel: you can reset the trip meter
in the standard displa ymenu
( Y page 128).
Vehicles with a 12-button luxury multi-
function steering wheel* :you can find th e
"Reset values" function in the Tripmenu in
the on-board computer (Y page 135). Controls

tilting sunroof* or panorama sliding sun-

this position when opened using the con-
venience opening feature. Residual heat/auxiliary ventilation
It is possible to make use of the residual heat
of the engine to continue heating the station-
ary vehicle for up to 30 minutes after the
engine has been switched off. The heating
time depends on the coolant temperature and
on the interior temperature that has been set.
i If you activate residual heat at high tem-
peratures, only the ventilation is activated.
i The blower will run at a low speed regard-
less of the airflow setting.
X Make sure the key is in position 0in the
ignition lock or that it has been removed. X
To activate :press the Tbutton.
The indicator lamp in the Tbutton is lit.

X To deactivate: press theTbutton.
The indicator lamp in the Tbutton is off.
The REST display message in the display is
not lit.
i The residual heat/auxiliary ventilation is
automatically deactivated after about 30
minutes, or when:
R the ignition is switched on
R the battery voltage drops
R the coolant temperature is too lo w Cooling with air-dehumidification
G
Risk of accident
If you deactivate the cooling function with
air dehumidification, the vehicle will not be
cooled in warm weather and the air will not
be dehumidified. The windows could mis t
up more quickly. This may prevent you from
observing the traffic conditions, thereby
causing an accident. H
Environmental not
e
The cooling system uses the refrigerant
R134A. This refrigerant does not damage
the earth's ozone layer.
i Condensation may drip from the under-
side of the vehicle when Thermatic is in
cooling mode.
Cooling with dehumidification is operational
when the engine is running, and cools accord -
ing to the interior temperature selected. The
air inside the vehicle is also dried, thereby
preventing the windows from misting up.
X To activate :press the œbutton.
The indicator lamp in the œbutton is lit.
The cooling with dehumidification function
is activated. Controls

Unscrew cap 1and remove it.
X Top up by the amount of oil required.
! Do not add too much oil. If too much oil
is added, there is a risk of damage to the
engine or the catalytic converter.
X Screw cap 1onto the filler neck. H
Environmental not
e
When topping up the oil, take care not to
spill any. Oil must not be allowed to escape
into the soil or waterways. You would oth-
erwise be damaging the environment . Coolan

Risk of injury
The cooling system is pressurised. There-
fore, only unscrew the cap once the engine
has cooled down. This means the coolant
temperature gauge must display less than
70 °C. You could otherwise be scalded by
escaping hot coolant.
Coolant consists of water and antifreeze/cor -
rosion inhibitor. Only check the coolant leve l
when the vehicle is on a level surface and th e
engine has cooled down. Checking the coolant level The expansion tank is located in the engin
e
compartment on the right-hand side of the
vehicle . 1
